INVALID-BED.

SPECIFICATION forming part of Letters Patent No. 740,867, dated october 6, 1903.

` Application iileii September 29, 1902. Serial No. 125.185. (No model.)

a citizen of the United States, residing at Rolla, in the county of Phelps, State of Mis# souri', have invented certain new and useful Improvements in Invalid-Beds, of which the followinglisl a specification, reference being had therein to the accompanying drawings.

This invention relates to invalidlifts or beds adapted to be packed for transportation andstretched for use.

The invention has for an object to provide a lift adapted to rest upon an ordinary bed and to be raisedl therefrom to allow defeca! tion of the patient without changing the re lations of the patient to this apparatus or any attached' fracture apparatus and for remaking or changing the bed'whenever desired, and also provides means for stretching the supporting fabric of the lift, so that it will be tense in a single plane, and thereby support the patient'inthe most desirable and com-Y Other and further objects and advantages.;-

of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure l is a top plan of the invention; Fig. 2, a bottom plan; Fig. 3, a vertical section on the line 3 3 of Fig. l;

Fig. 4:, an end'elevation showing the supporting means for the lift; Fig. 5, a vertical cross-` sectioh on the line 5 5 of Figgl, Fig. 6, a plan showingvthe opposite end bars folded upon the side barg'FigL 7, a detail perspective of the means for attaching the supporting fabric to the side bar; Fig. 8, a similar view of the adjusting means for one of the side bars, and Fig. 9 a detail vertical section on the line -9 9 of Fig. 2.

Like letters of reference refer to like parts in the severalgures of the drawings.

The lift or bed is composed of opposite side hars A and end bars B, connecting the same the supporting:

Y' at opposite ends, while a supporting body or fabric C, for instance, ot'- canvas, extends from one side bar t0 the other. One end of each of the end bars is secured to a fixed side bar by means of Aa bolt B', having at one end a suitable securing-nut B2 and at the opposite 'end an eye B3, adapted to receive the supporting means 'forthe lift, which may be of yany desired character-for instance, rods D,

having hooks D extending through the eyes B3 and provided between their ends With a block or pulley D2, while a double block D3 is secured to an overhead point of support, so

that the lifting-rope D, extending through the blocks or pulleys, may be operated to raise' the lift from the bed or support upon which it rests and then secured, for instance, to the belaying-pins B9 to maintain the lift in its raised position.. The opposite end of each of jthe end bars is secured to an adjustable side lLbar bya similar bolt B and nut B2, which pass through aslot B4, provided in the end bar, so as i to permit a lateral adjustment of the side bar 7A thereon. 'adj ustment a screw Eis provided and adapted For the purpose of securing this to pass through a, threaded lug or projection A' upon the cross-bar A, as shown in Figs. 8 and 9, the inner threaded end E' of said screw being adapted to operate in a recess B5 in the under face of the end bars B and to abut against a plate B6 at the end of said recess.

The opposite face of each end baris also provided with a recess B7, adapted to receive the projecting' heads of the screws E when the end bars are folded together, so that the end of one bar is lifted and dropped upon the other, asshown in Fig. 6, while this end of each end bar is provided with a guard-plate B?, having a guiding-aperture for the screw E. It will thus be seen that a rotationV of the screw will adjust the side bar A laterally of the opposite bar to hold the fabric C tightly in a single plane and support the patient without any sagging of the fabric.

At the center of the supporting fabric an aperture or opening C is provided to allow defecationV by the patient without moving the body and by simply raising the lift above the bed, `so that a suitable receptacle can be placed beneath the opening. In order to both protect the fabric about this opening IOO and also protect the patient from the .coarse fabric, a Waterproof covering C2, of any desired material, preferably oil-cloth, may be stitched to the opposite faces of the fabric adjacent to the opening C therein in order to permit its removal whenever desired. The opening in lthe oil-cloth is of less diameter than that in the fabric, so that the extended free edges of the oil-cloth at the opening may be cemented together, as at CX, to provide a smooth finish and obviate the use of stitching or other securing devices. Upon the under side of the fabric adjacent to this opening bracing-strips CS, of strong cloth, are extended laterally of the frame and similar strips O4, disposed diagonally thereto, as shown in Fig. 2, so as to prevent stretching or tearing of the opening, which would alloWa slack in the surface of the fabric adjacent tothe opening. The edges of the supporting fabric C may be secu red in any desired manner-for instance, as shown, they are bound j by a metal strip C5, having therein buttonholeslots C, adapted to fit over holding-pins A2 upon each of the side bars A, which pins may be adj usted in position. When the bars composing the frame are folded upon each other for transportation, the two bolts B', on one side of the frame, which are removed, may be disposed within properly shaped pockets F, formed on the under face of the end bars, and the washers or plates A3, removed from these bolts, may be placed within a pocket F', so that when the end bars are swung toward each other upon the remaining bolts B the upper surface of the side bar A will retain the articles within the pockets, while the projecting heads of the screws E will seat within the aperture B7, formed in the end of each bar, as shown in Fig. 6, by slightly lifting the free end of the end bar to spring the screw into the aperture. The adjustable side bar A, which has been removed to permit this folding, may be laid upon the other bars and the supporting fabric Wrapped around all of the bars, so as to form a very simple and convenient package, which can be easily transported for use in any place desired.

From the foregoing construction the operation of the invent-ion Will be clearly understood, and it will be apparent that the lift may be quickly assembled by any inexperienced person and by the simplicity of its construction and operation is adapted for use in any private dwelling as Well as in hospitals and similar institutions. The patient should be laid upon the supporting fabric, so that the end of the backbone will be above, not over, the margin of the aperture and the supporting fabric stretched tightly in a single plane, which holds the patient level, so that an examination by an attending surgeon can be made in the most convenient and thorough man ner possible and the patient kept in the same relative position to both the lift and the various surgical appliances which are attached thereto. The lift is adapted for use above an ordinary bed or couch and to be rested thereon when desired for warmth or change of pressure, but when it is desired to'relieve the patient from resting upon the bed for the purpose of treatment or otherwise the lift and patient thereon can -be readily raised by means of the block-and tackle to permit the treatment or for remaking the bed without disturbing his relations to the lift or to the surgical extension apparatus used thereon whether screws, weights, or l-Iodgin apparatus, all of which go up and down with him and the lift. This apparatus is particularly important for use in connection with fractures or broken limbs, in which the patient must be supported in one position for an extended time bystretching the cloth so tense as to hold the patient practically motionless or in a single plane, while the points of pressure are so changed as he islet down on different surfaces as to obviatc bed sores and give great comfort.

It will be obvious that changes may be made in the details of construction and configuration Without departing from the spirit of the invention and that the invention may be used in various manners for the treatment of invalids as conditions may suggest, it being especially designed to allow the use of various apparatus, whether inclined planes, pulleys, and weights, (Hodgin apparatus,) or screw extension, all of which can be easily attached to the woodwork of the frame and all of which go up and down with the patient and the lift.

Having described my invention and set forth its merit-s, what l claim, and desire to secure by Letters Patent, is-
